Description

Technical Field

[0001] This utility model relates to the field of mine lighting technology, specifically to a mine safety lamp. Background Technology

[0002] A mine refers to an independent production and operation unit that extracts ore within a certain mining boundary. It mainly includes one or more mining workshops (also known as pitheads, mine shafts, open-pit mines, etc.) and some auxiliary workshops. Most mines also include ore dressing plants (coal washing plants). During construction and operation, they need to use light sources for illumination, and special safety lights are often used for this purpose.

[0003] Currently, when using mine safety lights, in order to prevent the lamp tubes from being damaged by external forces such as gravel, they are usually protected by a transparent tempered glass cover and a metal protective net. Disassembly is difficult, and they are often directly welded or tightened with a large number of bolts and nuts. Therefore, it is very inconvenient to maintain and replace the internal lamp tubes, which greatly affects the effectiveness of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a mine safety lamp. By setting up multiple sets of clamping plates, pressure plates, springs, and fixing blocks, after the lamp cover and protective net are placed on the outside of the lamp tube, the clamping plates can be rotated so that the pressure plates on them press against the bottom side of the fixing ring, thereby clamping the clamping plates between the lamp holder and the fixing ring. With the clamping of multiple sets of clamping plates, the lamp holder and the fixing ring can be quickly fixed, and the lamp cover and protective net can be quickly installed on the lamp holder. Conversely, the clamping plates can be removed for quick removal. The operation is simple and quick, and it is convenient for maintenance and replacement of lamp tubes, greatly improving the use effect of the equipment and solving the above-mentioned shortcomings in the technology.
